DNA rings may detect early cancer, researchers find

In a new study, researchers have shown that an innovative technique— the use of DNA microcircles— has the potential to detect a broad range of cancers in the earliest stages by forcing tumors to create a unique protein.

The proof-of-principal study from Stanford University Medical School used DNA microcircles, a customized genetic construct consisting of tiny rings of DNA. After injecting the microcircles into mice, researchers used a blood test to show that mice with tumors produced a substance that tumor-free mic...
